Solar Wagon: tandem ebike and solar charging trailer — building a solar powered tandem ebike for my partner and I to go adventuring
QMB Prototype Demo — Lately, I've been having too much fun, working on quantum randomness generators. One of my goals is to build a minimalist device for producing a quantum binary outcome. I've designed one simple and cost-effective circuit ...
Quantum Coin Flip Device — Over the past few months, I've been working on building tools to connect human decisions with the outcomes of quantum measurements. The goal is to allow people to let their decisions be chosen using the ...
Bluetooth controlled Redbot construction — For part of the Ray elementary after school electronics and robotics club (R-ASER), I'm prototyping a robot that can be remotely controlled via a serial connection through bluetooth. The following is the rough draft of ...
ARFI: A Robotic Dog — Over the past couple of months, me and my friends at Artifice Tech Education have been building our very own robot dog mascot, ARFI. He's been a lot of fun to build, and although we ...
RASER Week 9: Laser activated trip wire — After last week's success with the physical trip wires, it's time to move on to some serious spy trip wire technology: LASERS! This project combines some of the tricks we've already learned as well as ...
RASER Week 8: Arduino trip wire — Today's project is a challenge to build a trip wire. The challenge builds on the Arduino input and output skills we put into practice last week. All we have to do is slightly adapt last ...
RASER Week 5 - Review Game — We've learned a lot so far in the RASER program by now. So to remind us about all of the things we've learned, we want to have a competition and see who remembers the most. ...
RASER Week 6: Arduino LED Passcode Pad - Part 2 — Two weeks ago, we started learning about one of the most important things Arduinos can do: read input voltages. We want to continue working on reading input this week and connect our input back to ...
RASER Week 4: Arduino LED Passcode Pad - Part 1 — This will be the first lesson where we really get into programming the Arduino to do something cool. The Arduino is an amazing tool for making devices that react to external inputs. In this lesson, ...
RASER Week 3: Arduino LED blinker — Electronics engineers can build really complicated devices by controlling when and where simple circuits turn on and off. For example, check out this flat screen monitor that I've opened up to see the inside. The ...
RASER Week 2: LED dimmers and switches — This lesson will extend our knowledge of electricity and resistance by adding variable resistors and switches. To start I want to show a Variac autotransformer. The dial controls the amount of electricity getting to the ...
RASER Week 1: LED circuits — In this lesson we'll learn how the electricity lighting up our gadgets flows through wires from batteries. My friend Pete built this amazing Jacob's ladder that we'll use to start off the lesson. The arc ...
RASER Curriculum — I'm running the Ray After School Electronics and Robotics (RASER) Program at Ray Elementary this Winter. The program is going to culminate with a competition on building an Arduino based security system. And each week ...
Solar battery charger & flower pot (first try) — This is my first attempt at attaching a solar battery charger like this one to a flower pot. The style of the pot isn't exactly what I was looking for. I was hoping to have ...
